Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | INPUT | power_in | Unregulated DC input supply. For a 9 V output, typical VI = 15 V (recommended VI range 11.5-24 V, absolute max 35 V). A 0.33 µF input bypass capacitor to GND is recommended close to the pin. |+| 2 | GND | power_in | Common ground / reference for both input and output. On the TO-252 package this pin is electrically common with the exposed thermal tab, which also serves as the primary heat-sink pad. |+| 3 | OUTPUT | power_out | Regulated +9 V output, up to 1 A load current (VO typ 9 V, 8.64-9.36 V at 25 °C). A 0.1 µF output capacitor to GND close to the pin is recommended for stability. Internally protected against short circuit (~800 mA into a shorted load) and thermal overload. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Unknown |+| Package | TO-252 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `78D09LL`++## CAD (KiCad official)++- Symbol: `78D09L`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Unknown datasheet](docs/78d09l-datasheet.pdf) (15 pp, sha256 `0816f246cc64ec64`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
